Does Phase 3 prepare you for Phase 4?

I’ve seen several posts on the subreddits mentioning they get burned out during Phase 4

With how easily you can handfeed the Space Elevator parts in Phase 1-3, I had no idea we were supposed to be automating multiples of every item in the game (one for Dimensional Depot, one for other machines)

So I found myself having to go back and redo my entire infrastructure to automate more items I should’ve done phases ago and improve efficiency

I also tried keeping everything in one central location but quickly got decision paralysis as to how to fit everything and bring every resource here, not knowing we were supposed to make several factories around the map. Or knowing how trains work.

The difficulty spike feels steeper also because of aluminum, rocket fuel, and nuclear production being more complex.

What do you think? Is the transition from earlier to newer phases fine as is, or could it use some tweaking?
